//1.axios前置拦截器：每次通过axios发送请求之前，让所有的请求都携带token
axios.interceptors.request.use(config => {
    //携带token

    if (token) {
        config.headers['token'] = token;
    }
    return config;
}, error => {
    Promise.reject(error);

//2.axios后置拦截器：后端处理完axios请求之后，处理响应的数据
axios.interceptors.response.use(res => {
    if (res.data.success === false && res.data.msg === "noLogin"){
        //删除localStorage的token和logininfo

//3.路由拦截器【拦截不到后端或不发送axios请求的请求】
router.beforeEach((to, from, next) => {
    //如果访问登录页面   或  注册页面
    if (to.path == '/login' || to.path == "/register") {
        next();//放行
    }else{//其他页面都需要判断你是否登录过
        //获取localStorage的登录信息
        let logininfo = localStorage.getItem('logininfo');
        if (logininfo) {
            next(); //登录过放行
        } else {
            //没有登录信息并且访问的不是登录或注册页面
            next({path: '/login'});//跳转到login - 登录页面
        }
    }
})

//router.afterEach(transition => {
//NProgress.done();
//});

//处理页面刷新动态路由失效问题
initIndexRouters();
function initIndexRouters(){
    if(!localStorage.menus){
        return;
    }
    //防止重复配置路由：5就是main.js中路由的个数 - 如果你的静态路由是6个这里要写成6
    if(router.options.routes.length>5){
        return;
    }
    let menus = localStorage.getItem('menus');
    menus = JSON.parse(menus);
    let tempRouters = [];
    menus.forEach(menu=>{
        let indexRouter = {
            path: '/',
